PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 605,350, dated June '7, 1898.

Application filed October 14, 1897. Serial No. 655,206. (No model.)

in Printing-Presses, of which the followingis a specification.

By means of this invention varying effects can be produced by the printing of certain impressions, upon some of which are superposed other impressions, as set forth in the following specification and claims 'and illustrated in the annexed drawings, in which- Figure 1 is a side elevation of a printing press or apparatus serviceable in carrying out the invention. Fig. 2 is a view like Fig. 1 with parts in a different position than in Fig. 1. Fig. 3 is a section along'w 00, Fig. 1. Fig. 4c shows a series of impressions.

A printing press or apparatus is shown with frame or support 1, having atable or carrier 2 for a web or sheet 3, coming from a roll or suitable supply 4 and fed by rollers 5. The rollers 5 can be rotated by hand or in any suitable way or any suitable feed mechanism can be employed.

A series of forms is shown at 6 7 8 9. These forms are suitably actuated, as by gearwheels 7 The gear-wheels 10 and 12, it is noticed, are

one half the size or diameter of the gearwheels 11 and 13, or said gear-wheels 10 and 12 rotate twice to every one revolution of the wheels 11 and 13.

Starting from the position shown in Fig. 1,0r with all the forms 6 to 9 out of action, the gear-wheels 10 and 12 upon completing a halfrevolution, as shown by full lines in Fig. 2, have actuated forms 6 and 8, so that the latter print or produce an impression. The gears 11 and 13 having now made only a quarter of a revolution, as seen by full lines, Fig. 2, the forms 7 and 9 do not yet print. 011 the gears 11 and 13 completing a half-revolution the I 7 forms 7 and 9 print, while the gears 10 and 12,

' having now completed a full revolution, have carried forms 6 and 8 out of action, as seen by broken lines in Fig. 2. Another half-revolution of gears 11 and 13 will return or carry forms 7 and 9 back to the position shown in Fig. 1, and such half-revolution of gears 11 and 13 being accomplished by a full revolu-v tion of the gears 10 and 12 the forms 6 and 8 will produce another impression by the time the forms7 and 9, with forms 6 and 8, have returned to the position shown in Fig. 1. In other words, the alternate forms 7 and 9 print half as fast as or with varying frequency from the adjacent forms 6 and 8. The alternate forms 7 and 9 canthus be made to successively print or impress upon and clear the impressions successively produced by the adjacent:forms 6 and 8.

Supposing, for example,the form 8 to have made one impression or print 011 sheet 3, such impression being fed under form 9 and'said form 9 being made to print and return, the print from form 9 will be superposed on the print from form 8. At the same time the form 8, as seen,'produces a second print and returns during the first print and return of the form 9. This "second print from form 8 can be allowed to clear or pass by form 9 without being impressed thereby, while the third print from form 8 again has a print superposed thereon by the form 9. Suitable alternations can thus beeffected, as indicated by Fig. 4, I

where the alternate prints 8 9 are intended to show the result of the superposed prints from forms 8 and 9, and the adjacentprints 8 are intended to show the result of the prints .from form 8 which have been cleared by form 9. In speaking of forms 8 and 9 it is understood that these forms alone suffice for the alternate printing described; but the addition of forms 6 and 7 enables greater variety or completeness or the printing of more coinplicated designs to be effected. Four forms 6 to 9 are shown in the drawings; but this number of forms can be varied. The forms can be colored for color-printing, or black ink can be used on all the forms if seen fit. The

inking or coloring of the forms can be effected I oo as frequently as the alternate forms 7 and 9 might be differently ti1nedas, for example, to print three times as frequently.

By having the crank-pins 15 each equally distant form the center or shaft of its respective cog-wheel 10 to 13 the throw or extent of movement of links 14 and forms 6 to 8 will be respectively equal. By having each cog-wheel 10 to 13 secured to ashaft, as seen at 18, Fig. 3, crank-pins 15 can be appliedat each side of the machine.

.In various kinds of printingas, for ex distant from the centers or shafts of their respective gears, the play or degree of motion of the respective printing faces or forms 6 to 8 will be equal, and in the construction shown when the crank-pins 15 are either in their highest or lowest positions the forms 6 to 8,

are on a level with one another.

What I claim as new, and desire to secure by Letters Patent, is

1. A printing-press having a succession of forms, actuating-gears of varying diameters for the forms, and crank-pins and links for connecting the forms and gears, said crankpins being placed equidistant from the centersor shafts of their respective gears substantially as described.

2. A printing-press having a succession of forms, a gear for each form, and crank-pins and links for connecting each form to its respective gear, said gears being made differential or variously speeded, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
